Definitions
- the present invention is directed to methods of controlling pathogenic fungi comprising applying sabadilla oil.
- Pathogenic fungi cause disease in plants and animals. Fungal plant pathogens threaten the yield and quality of agricultural crops costing farmers millions of dollars annually. Further, some fungal plant pathogens produce mycotoxins that are toxic to animals including humans. Fungicides have been developed that control the growth of fungal plant pathogens including those that produce mycotoxins.
- Fungicides play a critical role in maintaining a reliable and high quality food supply by protecting crops from fungal diseases.
- disease control has been achieved mainly by the use of inorganic and synthetic fungicides. These fungicides have been very effective and relatively inexpensive in controlling plant diseases.
- the reliance on fungicides for crop protection also led to the development of wide-spread fungicide resistance in pathogen populations globally.
- the wide-spread use of fungicides across most cropping systems and production acreage also created degrees of environmental disturbance and pollution.
- Fungicide resistance is a heritable change in the sensitivity of a pathogen population to the mode of action of fungicides, a change that could manifest itself either as a rapid failure of disease control or as a gradual loss of the efficacy of the compound over time.
- the most common mechanisms of fungicide resistance involve mutation(s) of the target site known as target site insensitivity. Mutation or alteration of the biochemical target site generally corifirms resistance to multiple fungicides that share a common mode of action (cross-resistance).
- the mode of action of modern fungicides is generally highly target site specific, and thus, these compounds are at a high risk for pathogen resistance due to mutation events occurring at the target site.
- additional mechanisms of documented fungicide resistance include the development of alternative metabolic pathways, increased rate of detoxification of the active ingredient, and increased removal of the toxic substance via diverse physiological mechanisms.
- Additional strategies also include seasonal limitations on the number of applications, use of mixtures of fungicides with different modes of actions, mamtaining the recommended dose range for the fungicide, the timing and method of application of the fungicide and the incorporation of non-chemical management tactics into the overall program.
- the primary tenet of resistance management is reduction of differential survival between resistant and susceptible genotypes by reducing the selection pressure exerted on the pathogen population by a particular fungicide.
- botanically-sourced active ingredients are generally readily biodegradable and significantly less harmful to the environment.
- plant derived pesticides usually comprise of an array of chemical compounds which affect a wide range of physiological functions in the target organism. As a consequence, the probability of resistance development against botanically sourced products containing a mixture of compounds is reduced.
- Sabadilla oil is an effective naturally derived pesticide found in the tissues of many of the plants of the genus Schoenocaulon, commonly referred to as sabadilla.
- Sabadilla oil is the byproduct obtained during extraction of alkaloids from the Sabadilla plant.
- Sabadilla oil does not contain the alkaloids, veratridine and verine.
- the species with the longest history of use, and the most readily available, is Schoenocaulon officinale. The plant is indigenous to Central and South America.
- Botanical pesticides are advantageous because they are biodegradable and significantly less harmful to the environment and users than synthetic pesticides. Thus, there is a need in the art for plant derived pesticides.
- the present invention is directed to methods of controlling pathogenic fungi comprising applying sabadilla oil.
- the sabadilla oil is derived from Schoenocaulon officinale.
- the present invention is directed to methods of controlling pathogenic fungi comprising applying sabadilla oil to the fungi's environment.
- Sabadilla oil may be derived from any species of Schoenocaulon. The genus
- Schoenocaulon includes the following species: S. calcicola, S. caricifolium, S. comatum, S. conzattii, S. dubium (alt. S. gracile), S. framei, S. ghiesbreghtii (alt. S. drummondii, S. yucatanense), S. ignigenum, S. intermedium, S. jaliscense, S. macrocarpum (alt. S. lauricola), S. madidorum, S. megarrhizum, S. mortonii, S. oaxacense, S. obtusum, S. officinale, S. pellucidum, S. plumosum, S.
- the sabadilla oil is derived from S. officinale. Further, sabadilla oil may be obtained from any part of the plant. In a preferred embodiment, the sabadilla oil is obtained from the seeds of the plant. In another preferred embodiment, the sabadilla oil is free of seed material including cellulose, hemicellulose, lignin and pectin.
- the term "effective amount” means the amount of the formulation that will control the target pest.
- the “effective amount” will vary depending on the concentration, the type of pest(s) being treated, the severity of the pest infestation, the result desired, and the life stage of the pest during treatment, among other factors. Thus, it is not always possible to specify an exact “effective amount.” However, an appropriate “effective amount” in any individual case may be determined by one of ordinary skill in the art.
- the sabadilla oil of the present invention may be included in a composition containing one or more excipients selected from the group consisting of solvents, anti-caking agents, stabilizers, defoamers, slip agents, humectants, dispersants, wetting agents, thickening agents, emulsifiers, penetrants, adjuvants, synergists, polymers, propellents and/or preservatives.
- excipients selected from the group consisting of solvents, anti-caking agents, stabilizers, defoamers, slip agents, humectants, dispersants, wetting agents, thickening agents, emulsifiers, penetrants, adjuvants, synergists, polymers, propellents and/or preservatives.
- the pathogenic fungus is a fungal plant pathogen.
- the sabadilla oil of the present invention can be applied by any convenient means.
- sabadilla oil is applied to the pest or the pest's environment at a rate from about 1 to about 100,000 grams per hectare ("g/HA"), preferably from about 1 to about 20,000 g/HA, more preferably from about 5 to about 10,000 g/HA and most preferably from about 50 to about 10,000 g/HA.
- g/HA grams per hectare
- compositions of the present invention comprise from about 0.05% to about 5.0% w/w sabadilla oil.
- control refers to killing, incapacitating, repelling, or otherwise decreasing the negative impact of the pest on plants or animals to a level that is desirable to the grower or animal.
- fungi's environment refers to any area that the fungi are present during any life stage.
- One environment likely to be treated by the methods of the present invention includes the plants and plant propagation materials that the fungi is living on and the surrounding soil.
- the fungi's environment may also include harvested plants, gardens, fields, greenhouses, or other buildings, and various indoor surfaces and structures, such as turaiture including beds, and furnishings including books, clothing, etc.
- Example 1 The objective of Example 1 was to evaluate the efficacy of sabadilla oil against naturally occurring Fuchsia rust caused by the fungal pathogen, Pucciniastrum epilobii on Fuchsia.
- Ta Mean % leaf area affected in treated plots after application
- Tb Mean % leaf area affected in treated plots before application
- Example 2 The objective of Example 2 was to evaluate the efficacy of sabadilla oil against naturally occurring powdery mildew infection caused by fungi in the Order Erysiphales on Dahlia.
- Sabadilla oil was applied as an EC formulation containing 70% sabadilla oil at 2.0 and 4.0% v/v concentrations.
- a total of five treatment applications were made at 7 days' intervals. All treatment applications were made using a pressurized CP 1.5 Cooper Pegler Compression Hand sprayer. The spray equipment was fully calibrated to obtain complete coverage of the plants.
- Each treatment was replicated five times. Each replicate consisted of one plant (Dahlia, cultivar Bishop of Canterbury), which were at growth stage BBCH 22-32 (two side shoots with two visibly extended internodes). The treatments were arranged in a randomized block design within the greenhouse.
